Description

FIREFLY Membrane WP is a non-combustible, fire resistant membrane that achieves Class A2 (EN 13501-1). Vapour permeable and suitable for use as a lining within ventilated facade systems, including applications above 18 metres.

FIREFLY MEMBRANE WP is a strong, breathable woven glass substrate aluminised on one side, suitable for jointing with foil tape.

Features and benefits:

Weatherproof and breathable, FIREFLY Membrane WP is designed to be a vapour permeable, reflective insulation layer in commercial facades and rain screen cladding systems.
Classified A2 (EN13501-1), suitable for use over 18 m – combining non-combustible fire resistance with traditional construction membrane performance requirements.
Ideal for upgrading fire performance both on remedial work and new installations of cladding and rain screen systems.
Outstanding strength and durability both before and after age testing, demonstrating sustainable performance attributes when weathered.
Lightweight, flexible, simple to install and resistant to damage during installation at temperatures as low as -40°C.
Jointed by foil tape.
